Blue Moonstone GemsMoonstone owes its name to the white, almost magical shimmer that resembles moonshine. Blue-whitish light glides over the surface when the stone is cut en cabochon. Gemologists call this phenomenon adularescence, which originates from the interior structure of the gemstone in scales or lamellas. Incoming rays of light are refracted inside the stone and scattered, creating a unique play of light, which makes moonstone so special and coveted. Moonstone has a Mohs hardness of 6-6.5, and is sensitive to pressure. However, it is still durable enough for many jewelry applications and makes wonderful necklace pendants, earrings and brooches.
